Abstract
An inductive battery charging system comprising a charge probe and a charge port that employs multi-turn spiral and helical windings in the charge probe to provide improved thermal management of the power produced by the charging system. The thermal management provided by the multi-turn windings of the present invention improves the power handling capacity of the system and reduces AC proximity losses. Numerous flat helical coil and spiral transformer windings are disclosed that provide for differing thermal management schemes. The present invention may be used to increase the inductive charging capacity of electric vehicle propulsion batteries to on the order of 120 KW. The present invention may be used with almost any transformer or inductor that uses foil windings.
